To all whom 'it may concern:

Be it known that I, HENRY TscHnnNlNo, citizen of the United States, residing at Freeport, in the county of Stephenson and State of Illinois, have invented certain new and useful Im rovelnents in Coffee-Mills, of which the ollowing is a specification, reference being had therein to the accompanying drawing.

This Invention relates to mills adapted to store material in a receptacle, above the grinding devices, the receptacle being closed above and so arranged that the ent-ire stock may be ground from time to time Without exposing the stock to the air.

It is desirable to use a transparent hper open and openable below only, but re mg such a receptacle has presented diiculties. My invention avoids these difficulties and at the same time permits using as a hopper an ordinary fruit jar which always shows the stock ori hand therein, and the construction is such that it ma be quickly replaced by the user of the millt in case it should be broken.

In the accompanying dra rings, Figure 1 is a front elevation of u mi l involving my invention. Fig. 2 is an inverted plan View of a neck to be secured ulpon the mouth of the jar or ho )per and to etachably connect the sume with the mill loper. Fig. 3 is an axial section of the neet in normal or noninverted position. Fig. 4 is a detail view of a stop device for a valve controlling the passage of material through said neck.

In these figures, A represents the body of the mill which is provided above with an open neck B. The hop er devices consist of an inverted glass jar secured to a neck l) which is n turn detarlmbly secured to the neck by means of n set screw E or other suitable device, so that the ent-ire hopper device may be readily removed us o whole from the body of the mill. lf desired, air excluding gaskets may be used at the joints for the more perfect exclusion of nir. For illustration, the neck l) is shown as having an oilset and a die hragm D' provided with a large central) opening to be closed when desired by a valve G mounted upon a rock shaft or the like F projecting on one side through the neck so that the valve ma be conveniently adjusted by the' hand. T e shaft is provided with stops H, I, `shown as integral, which limit the rocking of the shaft 1n either direction.

The parts beingassembled, with material in the hopper, t e valve may be opened whenever it is desired that the material shall pass to the rindin devices, and it may he so left unti the w ole stock of ma terlal has been ground. When the jar is to be refilled, the set screw is loosened and the hopper devices are detached as a whole and inverted. The valve then being open material is placed in the jar and the valve is closed, and while it is closed the jar is inverted and again secured to the body of the mill, with no possibility of spilling the material. The valve being again opened, the material passes into the mill and is ground in such quantities as may be needed.

Obviously the exact construction shown need not followed in embodying the invent-ion, it being not indispensable, for example, that the jar should be in threaded engagement with the neck, nor that this articuler type of valve should be used. t is however indispensable that the hopper closure should be removable with the jar and be o erable whether the jar is attached to the null or otherwise.

What I claim is:

1.. The combination with a mill casing having un opening above and u discharge opening below, of an upwardly closed hopper, un open tubular neck detacllobly lxed to and carried h the hopper and detachably secured to t 1c casing in registry with its npier opening and o volvo removable with tic neck and hopper nml controlling thc passage from the lutter into the casing, ifmbsllontiolly os ond for the purposes sct ort i.

In :n will of the dass de scribcd, the combnutiun with a casing fur grinding mcchuuism, of un open tubular neck llting and detaclmbly iixed in un npcnng in the upper art of the casing, an upwardly und lateral y closed hopper {itt-ing in and supported by the upper end of said neck, and n valve carried by the neck for at will opening und closing the pax-sage from the lmppvr lo thu grinding lnmzhunisul. In lestinmny whereof l uiiix my signature xn presence uf lwn witnesses.
